claims;` (o1. 15s- 75) The general object of my invention resides in the provision of a novel,` simple andeilicient oil burner and involves the mixture of steam, preferably superheated, with oil to produce an improved 5 combustion. f t

With this objectin view my invention consists in certain `features of novelty in the construction, combination, 4and arrangement of parts by which the said object and certain other objects, hereinafter appearing,` are effected, all as fully described with reference to the accompanying drawings and more particularly pointed out in the appended claims. i In the said drawingsv ,t Figure l is a condensed top plan view of an oil burner embodying my invention; y v y v Figure 2 is a partial condensed side elevation of thesame with parts broken away and shown in section; vt Figure 3 is a partial top plan section;

Figure 4 is a face view of one of the joint anges of the structure; i i Figure 5 is a partial section taken on the line Y 5-5 of Figure 2; l

Figure 6 is a condensed sectional view of the water inlet structure of the device, hereinafter described;

vFigure 7 is'an end elevation of a portion of the structure shown in Figure 5; and

Figure 8 is a section taken on the'line 8-8 of Figure 5. f Y

Like characters of reference indicate like parts in the several views.

Referring to the drawings, I designates a hollow header provided with a steam inlet 2 and twooppositely disposed outlets 3, seegFigures 1 and 3, and the header is provided with an interior partition structure 4 isolating the outlets 3 and provided with two valve ports 5 providing communication from the steam inlet 2 to the outlets 3 respectively.

` Two valve devices 6 are suitably mounted in openings in the front of the header l and include longitudinally movable valve `portions 1 cooperating with the ports 5 `respectively for regulating the ilow from the inlet" 2 to the outlets 3 respectively, the valve device 6 being adjusted by means of hand wheels 8.

` Two fuel charge forming and liberating devices or burners are associated one with each of the outlets 3, and each of these burners comprises the following parts:

A A hollow angle T fitting 9 has the middle portion thereof provided with a ange I I which has angular slots I2 therethrough and angularly spaced thereabout. See Figures 1,74 and 5. This middle portion of the fitting 9 is seated on the header I in coaxial continuing relation with an outlet 3 of the header, and is secured thereon by means of studs I3 secured on the header and 5 spaced about the outlet 3 and projecting through the slots I2 of the flange VI I and wedges I4 driven through holes in the studs and clamping the flange II between them andthe header. By reason of the slots I2, the fitting 9 may be angu- 10 larly adjusted on the header I for a purpose hereinafter described. f

. YA relatively large tube I5 is secured into one of the other openings of the tting 9 and projects therefrom, and a T angle fitting I6 is secured 15 at the third opening of the tting 9 in coaxial relation with the tube I5. A relatively small tube I'I is secured in the main bore of the angle tting I5 and extends therefrom within the tube I5, in coaxial spaced relation therewith. 20 See Figure 5.

The projecting or outlet end of the tube I1 is disposed inwardly of the corresponding pro'- jecting or outlet end of the tube I5 and is provided with an interior frusto-conical surface I8 25 -in the tube I5 adjacent the outlet end thereof and cooperates with the valve seat I8 of the tube I 'I, and is `provided with a square shank 24 movably engaging within the tube II. The stem 2| of the valve controlling device I9 extends within the tube I 'I and is secured to the shank 24 for regulating the flow from the tube II by the hand wheel 422.

The middle opening of the tting I6 is con- 40` nected by a pipe line 25 with a source of oil under pressure; the pipe line being provided with a shut oif valve 2B.

A sleeve 21 is disposed within the tube I5 immediately inward of the outlet end of the ,tube 45 Il and is secured on the tube II by means of a set screw 28,` see Figures 5'and 8, and this sleeve is provided withinterior and external flutes 29 which form multiple jets of Steam in the region of the outlet end of the tube I'I in the passage of 50 steamthrough the tube I5 toward its outlet end aswill be further described.

The valve head 23 is provided with an outer enlarged portion 3! within the tube I5, which is fluted, as designated at 32, see Figures 5 and 55 Cil '7, and provides a second multiple jet forming means outwardly beyond the outlet end of the tube il.

A steam generator is provided which comprises the following parts:

An upright pressure tight casing 33 is provided with a lower water inlet 3i and an upper steam outlet 35, and contained in the casing is a plurality of heat conductive elements 35, such as steel balls, providing interstices therebetween.

Water under pressure is ed'into the casing through the water inlet 34 by means of a pipe line 3l which is provided with a water regulating valve device including a valve seat 38, a valve head 39 on a stem il and a hand wheel 42 secured on the stem. See Figures 2 and 6. The pipe line 3l is also provided with a shut ofi valve 43.

Heat being applied to the casing 33, the water under pressure entering the same is converted into steam, the elements 35 within the casing accelerating the generation of steam in an obvious manner.

The steam outlet 35 of the steam generator is connected with the steam inlet 2 of the header I by means of a pipe M, and a pressure safety valve 45 on the header serves to release excess steam pressure.

The steam generator is disposed so that the outlet ends of the tubes l5 and Il are directed in the directionV thereof, the hereinbefore described pivotal adjustment of the tubes providing for adjustably directing the combustion from the tubes particularly with reference to applying the proper amount of heat to the steam generator, it being contemplated that the steam generator be disposed in a iire box with the tubes directed thereinto.

The operation of the burner isras follows. Assuming the steam generator to be heated, say by combustion from an intimate mixture of oil and steam, liberated from the outlet ends of the tubes I5, superheated steam under pressure from the steam generator, passes under regulation by the valve devices 5 into the tubes l5 and, passing through the flutes 29, issues immediately in front of the outlet end of the tubes l1 in the form of multiple jets. Oil under pressure, preheated by reason o the steam in the tubes l5 surrounding the tubes H and the flow of which oil is regulated by the valve heads 23, issues from the outlet ends of the tubes l 'l where it encounters the multiple jets of steam issuing from the flutes 29 of the sleeve 21 for intimate mixture therewith.

The mixture of steam and oil so formed then passes through the flutes 32 and issues from the outlet ends of the tubes i5 in the form of multiple jets where combustion takes place in the presence of air.

I do not wish to be limited to the precise details described as changes may be readily made without departing from the spirit of my invention, but having thus described my invention, I claim as new and desire to secure by Letters Patent the following:
